Meticulously designed industrial style and novel appearance are applied for cab. Load moment limiter display is confi gured to achieve the combination of main console and operating display system, making all operating condition data of lighting operation clear at a glance.

Hydraulic system High-quality key hydraulic components such as main oil pump, rotary pump, main valve, winch motor, and balancing parts etc. are adopted to achieve stable and reliable operation of the hydraulic system. Superior operation performance is guaranteed by accurate parameter matching.

Through the adoption of load sensitive variable displacement piston pump, pump displacement can be adjusted in real-time, achieving high-precision fl ow control, with no energy loss during operation;

Main valve has flow compensation and load feedback control function. It significantly enhances control stability for single action and combined action under different operation conditions.

Winch adopts electronically controlled variable motor, to ensure high operation effi ciency. Max. single line speeds of main and auxiliary winches is up to 125m/min;

Slewing system is equipped with the integrated slewing buffer valve, with free slipping function, to ensure more stable starting and control of the slewing operation and excellent micro-mobility.

Hydraulic oil tank capacity: 570L.

Control system CAN-bus instrument: CAN-bus instrument with a combined intelligent control electrical system is used for easy reading of the traveling parameters at any time. Engine fault warning function enables convenient and fast maintenance.

With full security protection system, main and auxiliary winches are equipped with over-roll out limiter and height limiters to prevent over-rolling out and over-hoisting of steel rope, including tip-over and limit angle protection.

Load moment limiter: The adoption of highly intelligent load moment limiter system can comprehensively protect lifting operation, ensuring accurate, stable and comfort operation.

The fault diagnosis system can detect superstructure electricity, hydraulic action, chassis (for major safety failure), engine and gearbox for fault to ensure reliable operation of the crane.

Telescopic system Four-section boom is applied with basic boom length of 9.9m, full-extended boom length of 31.5m, jib length of 16m and lifting height of fully extended boom length of 32.5m respectively. Max. lifting height is 46.5m including jib. It is made of fi ne grain high-strength steel, with U-shaped cross section and with telescopic operation controlled independent by double cylinder rope.

Luf� ng system Dead-weight luffi ng provides more stable luffi ng operation at low energy loss. Dual-action single piston hydraulic pressure cylinder with safety valve is adopted.

Luffi ng angle range is -3° ~ 80°.
